My first order for 2 replacement wings for the little Champ were completely demolished by the USPS. Dissapointed, I took pictures of the crushed box and of both wings as I was readying for a hassle. I am so pleased to tell you that one quick call to Customer Service and they shipped 2 new wings to me in 2 days, with no charge. Bravo! Didn't need the pictures or the stress. Hobby Lobby took great care of me! Thanks!

Pretty strong wing, it takes a pounding and keeps flying. I must have crashed mine 3 dozen times, rolled it through the weeds and across gravel, concrete, pavement and the wing is still in one piece.
Measures 18" x 3 1/4" x 1/8" at the widest and longest points.
The wing has markings as if there are ribs, it also has markings as if ailerons were able to be installed. I am not saying you should but I am sure if you knew how and could modify it, it may work.
The wind catches the surface really well on the wing, and in high wind it will carry the plane away. The wing is wide and thick and is pretty strong. Stability is really great in light winds, and in no wind situations, the wing is really great and so far I have never seen issues that would really need repairing.
As I said I crash often and roll the wing across the ground many times, and scrub across pavement too, and the most I have seen is some small denting and scratches, no breaks or ruptures.

Down side, the wing has no ailerons, it is less maneuverable and will not allow barrel rolls, corkscrew, or Immelman maneuvers. The wide area has a wind catch that slows flight and makes the plane less stunt worthy. For park flyers and beginners however it is good. Strong so you do not trash the wing in impacts.
